In plain words
The Rāmāyaṇa explained the truth of what good name the unity among brothers, the bond of affection and the principle of Prema went on earning for a family. The maker of such a Rāmāyaṇa, its creator, is Vālmīki. Rāvaṇa flourished in every fortune; there was no lack of any kind in his enjoyments and riches. His equal was not to be seen anywhere in the world. He was a man of great power who had studied the sixty-four branches of learning. The city of Laṅkā was such as to make one forget even heaven. What is the inner meaning of Vālmīki's showing no regard for such a Rāvaṇa and caring only for Rāma, who gave up the kingdom, …, lived in the forests, wore the garb of an ascetic and spent his life so? Rāma is the embodiment of Dharma. Every single thing he did was steeped in Dharma. Every word he spoke was the very form of Satya. Every step he took fell upon Dharma. So they said, rāmo vigrahavān dharmaḥ. What is the inner meaning of this maharṣi's setting no store by wealth, gold, goods and vehicles, setting no store by strength of arm and strength of intellect, and caring for Dharma? For the world, for human life, for humanness itself, Dharma alone is the life-breath. They went on bringing home the truth that Dharma alone is the foundation.
For human life the four puruṣārthas are the chief principle. Among those principles too, the very first is Dharma. After it, artha and kāma. Only when artha and kāma follow Dharma do they too bear fruit; but when we give up Dharma and enjoy artha and kāma, they bring nothing but distress. So artha too must be steeped in Dharma. Our desires too must be steeped in Dharma. Then the Mokṣa we long for becomes our aim: this is what these puruṣārthas have gone on teaching so well. But today, by misfortune, the people of Bhārata have cut off, of the four puruṣārthas, Dharma, artha, kāma and Mokṣa, the feet that are Dharma and the head that is Mokṣa, and are living their lives holding on to the trunk that is artha and kāma. Because of this the land of Bhārata today has had to fall into so many kinds of sorrow.
